std: Doc blocking behavior of LazyLock methods

Rollup merge of #109318 - joboet:better_fmt_placeholder, r=dtolnay

2023-07-31T20:51:12+00:00

Make `Debug` representations of `[Lazy, Once]*[Cell, Lock]` consistent with `Mutex` and `RwLock` `Mutex` prints `` as a field value when its inner value cannot be accessed, but the lazy types print a fixed string like "`OnceCell(Uninit)`". This could cause confusion if the inner type is a unit type named `Uninit` and does not respect the pretty-printing flag. With this change, the format message is now "`OnceCell()`", consistent with `Mutex`.

Rollup merge of #109075 - joboet:lazylock_backtrace, r=workingjubilee

Use `LazyLock` to lazily resolve backtraces By using TAIT to name the initializing closure, `LazyLock` can be used to replace the current `LazilyResolvedCapture`.
